Description
We examine $\Upsilon(1S)$ meson decay into a pair of
scalar Dark Matter particles and $\Upsilon(3S)$ meson decay into a
pair of scalar Dark Matter particles and a photon. To the lowest
order in perturbation theory, we perform model-independent analysis
and derive formulae for the branching ratios of these decays. We
confront our calculation results with the experimental data. We do
it both in the model-independent way and within particular models.
This way we derive constraints on parameters of the models
containing light Dark Matter.
